How to change page title in browser window?

Hello,

currently in the browser window my records title is as follow

record title - category title - menu item title - site name

I would like to change it to

record title - site name

but I can't find a way to do this

the reaosn is shared content in facebook doesn't look very good, the title string becomes long

I looked in joomla configuration but I don't think the setting is there, there I found only a setting to put the site name after the content title

thank you
